KB73343332Here’s some information on a new Knowledge Base article we published. The symptoms of the issue are as follows:

Any Microsoft System Center Virtual Machine Manager (VMM) activity (such as a copy routine) that involves moving data that includes files such as .vhd, .vhdx, and .iso files fails as soon as the job begins to move data.

The following VMM trace example shows a Background Intelligent Transfer Service (BITS) copy job beginning. First, locate the exception (HostAgentFail (2912); HR: 0x80041001) at the bottom of the stack, and then start examining the events before the exception. The first line shows that BITS is starting a copy job: at Microsoft.VirtualManager.Engine.Deployment.BitDeployer.Copy().

*** Carmine error was: HostAgentFail (2912); HR: 0x80041001

This problem occurs when BITS has a job suspended on the VMM server or the host to which data is being transferred. These jobs must be removed to enable other BITS jobs to run.

For all the details and a resolution, please see the following:
